"en of my invention,

the same.

c indicate correaiiwigures oi the and Fig. 2 is an end 'i Les* ifi' Similar letters of sponding parts in t tf, drawin 'lhc object oi' my iixagentiopdiis .,tolprovide a device by thc use of which 'the'wires used in building` fences may be properly and irmly tightened; and the improvement consists in a metal fran'ie, within 'ivii'cliI is secured a shai't or spindle, around which. 'one end of the wire is wound by .revolving the same.

It also consists in p viding the said shaft or spindle @with a clnll vinili engages with a corresponding cluticl ir oii'the frame, by which tl,,ic"pro.per teni p dei; the wire is secured.

In the drawing, Afreireisents the metal frame, which has air eliptial, form, and is provided atene endj artid within which is a` longitudin eggyeoifchannel, a, extending through th` R loi li'elframe. The frame is provided at 'Fi 'side with a clutch, U, within whirll spindle, "D, efvtending n; tted a shaft or ,nd 1thron gh the frame, and is t secure ilegal, `1n a manner which admits ot' a revolving movement. end of said spindle is made in a square form, and is provided with a clutch, C', which is loosely fitted and so arranged as to engage with the clutch C of the frame. The said spindle is provided upon one side, near the outer surface of clutch G, with a lip or projection, d, by which the clutch is secured upon the same, the distance of the lip from the clutch being such as to allow the said clutch a slight rocking motion, which, together with a slight longitudinal movement of the spindle, allows the teeth of the clutches to pass each other as the spindle is revolved in the proper direction to tighten the wire.

The operation of my invention is as follows: One end of the wire to be tightened is drawn through the groove or channel a and passed through an aperture in the spindle. One end ot' the frame is then made fast to the fencepost by a wire, E. A crank is then applied to the spindle, giving the saine a rotating movement, by which the wire is wound around the spindle until the same is properly tightened` The clutches C C' are then engaged, by which means the tension of the wire is secured.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The frame A, provided with the groove a and clutch C, in combination with the spindle i D and clutch C', substantially as described.

ALBERT BYINGTON.
